...dard error. It becomes a "journey" to plot a simple graph (e.g. https://www.r-bloggers.com/building-barplots-with-error-bars/). The same way that is easy to use the boxplot function, do you think it is possible to upgrade the barplot function: i.e.: barplot(Spores~treatment, error.bar=standard_error, col=treatment_colors) Thank you so much!

...would it make sense to get standard error for posterior probability from lda() and how? Another question about standard error estimate from glm(): is it ok to calculate 95% CI for the predicted probability using the standard error based on normal apprximation, i.e. predicted_probability +/- 1.96 * standard_error?

While you are editing that, you might change its name from 'stderr' to standardError (or standard_error, etc.) so as not to conflict with base::stderr().

Further, he is probably right about no changes after this many years. I might mention that...

In "An Introduction to R" Version 3.3.1, in "4.2 The function tapply() and ragged arrays", after stderr <- function(x) sqrt(var(x)/length(x)) , there is a note in brackets: Writing functions will be considered later in [Writing your own functions], and in this case was unnecessary as R also has a builtin function sd(). The part "in this case was unnecessary as R also
